Setting the Mortise Depth
The mortising depth determines how deep into the workpiece the mortising bit penetrates. This needs to be adjusted for different sized tenons. In most cases, the tenon should be centered across the joint, and the depth of the mortise should be ½ the length of the tenon. However, in some cases you may want to have more of the tenon in one piece than the other (lower Domino tenon pictured below). In this case, the sum of the two depths must equal the length of the tenon. (In the offset tenon example below, the Domino tenon is 40 mm long, the left mortise is 28 mm deep, and the right mortise is 12 mm deep.)
1.Press in on the depth adjust lock.
2.Move the depth adjust lever to the stepped position of the desired depth.
3.Release the depth adjust lock.
Changing the Mortising Bit
Different mortising bits are available for a variety of Domino tenon sizes. The DF500 comes equipped with a 5mm bit, and 6, 8, and 10 mm bits are available as an option.
WARNING: Always unplug the tool before changing mortising bits, or removing the fence body from the motor housing.
1.Using the provided 8mm wrench, pry up on the fence body release lever, and slide the fence body off the motor housing. (The inset photograph on page 6 shows the fence body and motor housing when separated.)
2.Press and hold the spindle lock button. This stops the spindle from turning while you loosen the mortising bit.
3.Loosen the mortising bit by turning it counterclockwise (standard
4.Insert a new mortising bit, and start the threads by hand to avoid
5.Press in on the spindle lock while tightening the bit. Do not over tighten the bit.
6.Carefully reinstall the fence body onto the motor housing, and push the fence body in until the latch clicks.
►Make sure there is no sawdust inside the guide tubes before inserting the fence body.
►Be careful not to damage the linear bearings (hollow tubes) when reinstalling the fence body. If it does not slide on easy, it means the fence is skewed with respect to the bearings.
